“I think he goes from apartment to apartment doing this. He knows the law. He knows what he’s doing. He knows it will take me six months to get him out.”

Wiley, 33, weaseled his way into the $1,600-a-month, two-bedroom apartment in Woodside earlier this year after the pad’s female tenant took him on as a roommate.

“He was fine until he stopped paying the rent,” griped then-roommate Shannon Rogers, who claimed that Wiley also stiffed her on his half of the utility bills.

Karakas’ troubles started when Rogers’ lease expired in late April and she turned over her apartment keys to Karakas’ father, Laszlo, 78.

Laszlo then went to the third-floor apartment expecting to find it empty — but instead saw Wiley making himself at home, Karakas said.

Wiley told the older man that he was Rogers’ roommate and politely asked for time to clear out, the landlord said.

Days later, Wiley changed his tune, saying he planned to rent the apartment with his brother, Karakas said. But he failed to fill out an application or provide a down payment.

Karakas said that so far he is out $6,400 for the past four months’ rent and about $1,000 in legal fees trying to boot Wiley, who was served formal eviction papers in June but won an extension until the end of last month, claiming he’d been scammed out of $600 trying to rent another place.

Meanwhile, Wiley has been reaping in the big tips as a waiter and bartender at the posh Prime House on Park Avenue.

Wiley was Cary Grant-charming last week when he served a Post reporter a soda, French baguettes and Prime House butter in a ceramic cup.

He was later spotted counting a wad of tip money.

But the next day, he was pure Alec Baldwin, angrily grabbing a Post photographer’s camera outside his rent-free abode.

He refused to comment.

Karakas said he just wants the squatter out — but admitted he is stunned by Wiley’s wile.

“He’s always cool, very slick, never angry,” Karakas said.

Even when a fed-up Karakas changed the lock to the front entrance of the tidy, three-family brick house on 58th Street in the spring, it was Wiley who called the cops, Karakas said.

The officers allegedly told a shocked Karakas to hand Wiley a set of new keys — and try to evict him in housing court if he wanted.
